Embodiment Construction

[0029] In a preferred embodiment of the method, the applicator comprises:

[0030] (i) a punching machine having a punch,

[0031] and

[0032] (iii) pad take-up rolls,

[0033] Wherein, in this method, the die-cutting belt runs on the punch of the punching machine, when one of the die-cut parts is on the punching head, the die-cutting belt is stopped, and then the punching machine sticks the die-cutting parts in an up and down motion. attached to the surface.

[0034] If the ratio of the pull-off force of the die-cut from the backing layer in z-direction to the pull-off force of the die-cut from said surface in z-direction is at most 0.15, preferably at most 0.12 and more particularly at most 0.10, then is particularly beneficial.

[0035] The method of the invention is suitable for both manual and automated application of die-cuts. In the particular case of automated application, the method according to the invention entails great advantages, since here special emphasis...

Abstract

Systems and methods transfer diecuts from a liner layer to a surface. One method may transfer a diecut from the liner layer to the surface by means of an applicator, wherein a ratio of the pull-off force of the diecut from the liner layer in the z direction to the pull-off force of the diecut from the surface in the z direction is at most 0.18. The method may enable particularly reliable and firmtransfer of the diecut from a diecut tape to a surface where bonding is to take place. As a result, it may be possible for the frequency of errors in the bonding of plastics parts to be relevantly reduced.

Description

technical field [0001] The invention relates to a method for transferring die-cuts, ie die-cut parts, from a backing layer to a surface, the die-cuts being transferred from the backing layer to the surface by means of an applicator, characterized in that the die-cuts move from the backing layer to the surface in the z-direction The ratio of the pull-off force of the mat to the pull-off force (separation force) of the die-cut from said surface in the z-direction is at most 0.18. The invention further relates to a test method for selecting an adhesive tape as a die-cut tape to transfer a die-cut piece from a backing layer to the surface of a substrate (substrate) by means of an applicator, the die-cut tape being formed by a die applied on the backing layer. A die cut is formed comprising at least one adhesive composition (ingredient) layer. Background technique [0002] Adhesives and tapes are commonly used to assemble two substrates to form a durable or permanent bond. Desp...
